How to use a green screen in OBS and XSplit

A green screen is a great way to add a little extra production value to your streams. Here's how to get started.
If you're a frequent viewer on Mixer or Twitch and wonder how your favorite streamers have managed to make their backgrounds disappear from around them on camera, chances are they're using a green screen.
There are cameras out there that will do it through software (Logitech's C922) or by using Intel RealSense (Razer Stargazer), but to do it with any camera and with minimal impact on your PC a green screen is a great way to do it if you have room.
Allow me to walk you through the steps of setting up a green screen for use in both OBS Studio and XSplit.
